Dhak Dhak takes four stranger women on a road trip. One is a vlogger going through an identity crisis after invasion of her privacy. The other is an elderly woman who happened to win a bike in a competition. Then there is the scared girl whose marriage is fixed and is confused about her future. Lastly, a bike mechanic in a toxic marriage who wants to provide for her daughter. How these four come together to go on a biker's pilgrimage and what challenges they face during their journey to the destination as well as gaining strength to stand up to their personal lives' issues.
It is the performances especially from Ratna Pathak Shah and Fatima Sana Shaikh that carried the film whereas Sanjana Sanghi and Dia Mirza got the most impactful scenes. The characters' backstories were slightly underwritten and it tackles the emotions mostly on the surface level. Winning a bike in a lucky draw alone wasn't enough to justify the long ride to the biker's haven, leaving much of it to Ratna Pathak Shah to make it work. Despite it's shortcoming, the film definitely worked in parts and I wished the final act was handled better instead of throwing in quite a lot right from the monk to tackling the family members when one's life was at stake.
